## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "What can I say! Liam, Keiron and Bernie were professional, understanding and helpful during our works: Replacing a 25 year old girder supporting our main bedroom. They explained the process at each stage. We felt confident with their knowledge and experience dealing with a complex situation and the works completed to a high standard. We will definitely use them again and recommend them."

> "After buying a house with many problems i contacted TRI DYN & I'm so glad I did. Throughout the whole process there was good communication, good time keeping, always friendly, honest, tidy & polite. I had a leaking wet room that needed taking out & a new bathroom installed. I couldn't be happier. Liam & Sian work there socks off & are a great team! Always giving me the best advice along the way. I also found a leak on the chimney & condensation in the attic. Again I called TRI DYN & the knowledge, experience & workmanship was brilliant. I can't recommend these guy's highly enough!"

> "What can I say other than I would beyond recommend Liam. From the moment he came to give me a quote and look at the job I had a good vibe from his friendly attitude to his expertise when I was asking questions. The work was carried out efficiently over 2 days as agreed. The areas were left clean after each day and most importantly the work was completed to a high standard. I can not recommend Liam enough. Such a nice guy with great silicone skills which is very important to me. Approaching Liam throughout the job was never an issue and my happiness with the work was his priority."

## Before you hire a builder
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
- Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
- Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work — and that they are current.
